if you expect a map behavior, why not using one ?
std::map<CString, CString> mapKeyValue;
<font color=green>
mapKeyValue[<font color=gray>"key1"</font>] = <font color=gray>"value1\r\n"</font>;
mapKeyValue[<font color=gray>"key2"</font>] = <font color=gray>"value2\r\n"</font>;
mapKeyValue[<font color=gray>"key3"</font>] = <font color=gray>"value3\r\n"</font>;
<font color=green>
<font color=blue>int</font> iChoice = Rand123(); <font color=green>
CString strRandomValue;
strRandomValue.Format(<font color=gray>"key%d"</font>, iChoice);
strRandomValue = mapKeyValue[strRandomValue];

Hello everybody,
Could anybody let me know how to use unique member function of list template class in STL? My problem is, I have a C++ class, Complex, which has two data members, real and imaginary numbers. I am using Complex class in creating a list. How can I use unique member function of list class when I have created a list using Complex class?
Grateful to you,
Thanks,
Software Developer

list::unique works on sorted ranges, so that might explain why you think it doesnt work.
#include <iostream>
#include <list>
//#include <complex>
using namespace std;
struct Complex
{
Complex(int a, int b): i(a), r(b) {}
int i;
int r;
bool operator < (const Complex&c)
{
if (r != c.r)
return r < c.r;
else
return i < c.i;
}
bool operator == (const Complex&c)
{
return r == c.r && i == c.i;
}
friend ostream& operator << (const ostream&out, const Complex& c);
};
ostream& operator << (ostream&out, const Complex& c)
{
out << "(" << c.r << "," << c.i << ")";
return out;
}
int main()
{
list<Complex > l;
for (unsigned int i = 0;i<10;++i)
l.push_back(Complex(1+i%2,2+(i+1)%3));
copy(l.begin(), l.end(), ostream_iterator<Complex >(cout, "\t"));
cout << endl;
l.unique(); // unsorted list, chances are that no elements are equal to its preceding neighbor
copy(l.begin(), l.end(), ostream_iterator<Complex >(cout, "\t"));
cout << endl;
l.sort();
copy(l.begin(), l.end(), ostream_iterator<Complex >(cout, "\t"));
cout << endl;
l.unique();
copy(l.begin(), l.end(), ostream_iterator<Complex >(cout, "\t"));
cout << endl;
return 0;
}

I'm trying for an ATL Component with Containment. but i get the following error.
[error]
error MIDL2025 : syntax error : expecting a type specification near "IIACall"
[/error]
and this comes from the IDL code ,
[IDL]
[propget, id(7), helpstring("property ActiveCall")] HRESULT ActiveCall([out, retval] IIACall* *pVal);
[/IDL]
IDL code displayed is 'Outer' interface.
IIACall* is the pointer to inner interface.
Thanks,
Vivek
oops, i type so bad today

I see! I've been mostly invisible here because of my recent workload. When I get home at nights I'm either working or just haven't got the will/power.

Q) When I create any damn ATL Project, using ATL wizard in WINXP/SP2 - I choose simple SIMPLE OBJECT (from object category) after adding methods to interface and compiling and registering using tool->register control OR using REGSVR32.exe "xx.dll", It tells me ok registered successfully. Butwhen i CoCreateInstance(...) it ives me this error. hr = -2147221164 i.e "Class not registered" When i drag it in VB i get error cannot load dll. When i view using ACTIVEX Control Test container, it dosent shows me my class!!! BUThowever if i do use FULL CONTROL using ATL wizard It registers successfully and even i can load it in VB So what mus be the problem with SIMPLE OBJECT
What must be the problem, any genuine solution!!!!

The easiest way is probably as a SAFEARRAY in a VARIANT.
Use the SafeArray* functions to create the SAFEARRAY.
Then put the array into the variant using VT_ARRAY|<array element="" type="" index=""> as the VARIANT type.
HTH.

In ATL there is a wrapper class for SAFEARRAYs called CComSafeArray. It simplifies using of arrays in COM.

Hi All,
i have made a Customized Webbrowser using ATL in VC++ ,we have used IE Control & IWebBrowser2 interface for this, the browser is working fine, but the major problem is The context menus on the webpage(eg:when u right click on the webpage the menu like Undo,Cut,Copy,Paste,Delete,SelectAll will be displayed)
in these Cut& Copy are not working, r
emaining all are working fine..
when i have used the Command of IOleCommandTarget Exec method
ex: i did Like
CComPtr<iwebbrowser2> m_spBrowser;
CComPtr<iolecommandtarget> pComTarget;
m_spBrowser->QueryInterface(IID_IOleCommandTarget,(void**)&pComTarget);
pComTarget->Exec(NULL, OLECMDID_PASTE, OLECMDEXECOPT_DONTPROMPTUSER, NULL,NULL);
pComTarget->Exec(NULL, OLECMDID_PASTE, OLECMDEXECOPT_DONTPROMPTUSER, NULL,NULL);
by using this method all operations working fine except CUT& COPY
Please i need help Regarding this,
Thanks

Has anyone successfully built the boost library using VS2005?

Have you tried and failed? In theory it's supposed to work, according to the Boost page.

Tried with 1.33. Most of it built but some of it didn't and there were some buffer overruns during the build. I might try one of the betas.
Thanks!

With beta 2, yes.
I just used bjam with a toolset of "vc-8_0", like it says on the Getting Started page. At that time, there were a few problems -one of the libraries wouldn't build (but I didn't need it) and also they tried to build a statically linked or single-threaded CRT version when there isn't one.
Anyway, it just worked?

Didn't use the beta. I used 1.33. Several buffer overruns and as you stated some of the libraries didn't build.
Moving to the beta!
Thanks.

Bit of a misunderstanding - I meant I'd used beta 2 of Visual Studio 2005, rather than the retail version...I've only built released builds of 1.32 & 1.33, no betas.
Sorry for any confusion!

I have built boost_python and boost_signals with VC 2005 Express without problems. The other libs did not compile. (boost_1_33_0).

I solved the problem. The problem is the order in which these libraries are inlcuded. I got a good article from Codeguru which helped me to solve this bug.
this is the link[^]
Anyway Thanks,
